Title: Improved apparatus for the mixing of a liquid with a solid or a liquid with a liquid
IPC: B28C5/12
Filed: 1945-05-29
Abstract: 593,270. Mixing-machines. MORGAN, J. S., and GAMMON, J. C. May 29, 1945, No. 13398. [Class 86] Apparatus for mixing cement grout comprises a rotary drum 2, Fig. 1, disposed within a container 1, and partially surrounded by an eccentrically disposed curved plate 8 which is supported on a pivot 10. The container 1 is partly filled with water, and cement is gradually added whilst the drum 2 is rotated to project a tangential stream of the mixture through the gap between the drum and the lip 9 of the hood 8. The width of the gap is adjusted by the movement of the hood 8 about its pivot 10 on rotation of a cam 11 about a shaft 12. The edge 14 of a baffle plate 13 is adjustable with respect to the drum 2 whereby the amount of material carried around by the drum 2 may be varied. An electric motor or other prime mover drives the drum 2 from a driving shaft 7 through a belt and pulley gearing. The discharge of the mix may be effected through an opening in the bottom of the casing controlled by a sliding plate, or the casing 1 may be tiltable about trunnions coaxial with the drum 2. In a modified construction the casing is in two parts of substantially volute cross section, and rollers rotate in opposite directions to project two tangential streams from beneath the deflector plates to impact one against the other. In a further modified construction rollers 32, 33, Fig. 3, rotate in the same direction to project tangential streams from beneath fixed or adjustable deflector plates 36, 37. Separate ingredients, such as cement and water, and sand and water, respectively, may be fed into the two compartments 30, 31, which are separated by baffles 38, 39. The baffle 39 may be turned about a pivot 40 so that the mixture in the compartment 30 may be transferred to be mixed with that in the compartment 31. In both modified constructions discharge, may be effected through openings controlled by sliding plates or valves or by tilting the container.

Abstract: 1,060,761. Cable twisting machines. SOC. ANON. GEOFFROY-DELORE. April 1, 1964 [April 11, 1963], No. 13523/64. Heading D1T. A machine for making multi-layer cables Fig. 1a draws its core filaments 2 from fixed supply units 1, the core filaments being drawn through a distribution grid 4 and a die plate 5 before entering a twisting tube 7 that is coaxial with and rotates in synchronism with a further twisting tube 13. Freely suspended on the tubes 7, 13 in a non-rotating cradle 19 carrying a plurality of filament supply units 21. The twisted core 6 in the tube 7 is withdrawn from one side of the tube 7 and then guided past the cradle 19 by pulleys 20a to c. Pulleys 20d, 20c then guide the core 6 in the reverse direction through the tube 13 and back into the twist tube 7 where the filaments 22 from the cradle 19 are fed through a non-rotating grid 25 and then stranded onto the core 6. The resulting cable 27, in the twist tube 7, passes out through the side of the tube 7 and is guided past the cradle 19 back into the tube 13 by pulleys 20a, 20e, 20f. The pulleys 29a 29b prevent undue distortion of the core 6 and cable 27 by centrifugal' forces. There may be a plurality of the pulleys 29a, 29b between the tubes 7 and 13. Further layers may be added to the cable 27 by extending the machinery to include, for each layer, further rotary units comprising twisting spindles 7, 13, with their associated cradle 19 and pulleys 20a to f, 29a, 29b. When the resulting cable leaves the last of the rotary units described above it may be directly taken up by a receiver assembly R, Fig. 1b. Alternatively, a plate or cage 31 rotating with the cable 27 carries a plurality of spools 33a, 33b and pulleys 35a, 35b that distribute strands 34a, 34b around the cable without strading them. The resulting assembly passes through a distribution grid 40 receiving strands 42 from a stationary supply 41, there being a die plate 43 by which the strands 42 are wound around the cable 27 and the strands 34a, 34b. When the resulting assembly leaves the die plate 43 it passes through a member P that gives the cable a sectoral form, for example by hammering or rolling the cable, before being wound up on the drum T.

Title: Improvements in and relating to earth leakage protection systems for electric motors, cables and other apparatus
IPC: H02H11/00
Filed: 1947-05-28
Abstract: 623,911. Protective cut-out arrangements. BROOKE, W., and BALDWIN, H. T. May 28, 1947, No. 14151. Addition to 605,927. [Class 38(v)] In a modification of the earth leakage protection system of the parent Specification alternative means are provided to prevent the reclosure of the circuit breaker or contactor while a fault persists, and comprises a lockout or leakage relay energized directly or indirectly through the fault path. Fig. 1 shows a motor B controlled by a contactor C which' closes under the action of its coil C<SP>4</SP> when a gas-filled triode J fires on the closing of a switch D as described in Specification 568,336. In the event of an earth fault, say 12c on line X, a circuit is established from connection C<SP>1</SP> through neutral point inductance A, changeover switch C<SP>5</SP> operated by contactor C, line 13, relay coil S<SP>2</SP>, line 14, earth and fault path 12c to line X, the potential established across the inductance A operating the relay S to open contacts S<SP>1</SP>. This interrupts the current through coil C<SP>4</SP> and the contactor C opens to protect the motor B. At the same time the switch C' connects the inductance A to the coil R<SP>2</SP> of a relay R which is now energized by the secondary winding F<SP>5</SP> of a transformer F through the fault path. Contacts R<SP>1</SP> open to prevent the re-energization of coil C<SP>4</SP> and contacts R<SP>3</SP> close to light a fault indicating lamp E which is supplied from a secondary winding F<SP>6</SP>. When the fault is removed the relay coil R<SP>2</SP> is de-energized and contacts R<SP>1</SP> reclose to permit the reclosure of the contactor. In a modification (Fig. 4, not shown), the relay R may be energized by the anode current of a further triode having its bias system controlled through the fault path. This overcomes the need for the operating current of relay R to pass through the fault path. In Fig. 2 a second triode K and inductance AA are used instead of relay S. When a fault occurs the bias resistance La of the triode K is parallelled by an inductive circuit comprising line 22, switch C<SP>5</SP>, inductance AA, line 24, line X, fault 12c, earth and line 25. The triode K fires, energizes relay R to open contacts R<SP>1</SP> so interrupting the anode current of triode J and opening the contactor C. While the fault remains, the reclosure of the contactor is prevented as the operation of switch C<SP>5</SP> has re-established the inductive biasing circuit through inductance A. Fig. 3 (not shown), illustrates the application of the latter arrangement to a circuit having a manually closed circuit breaker with a " no-volt no-close " coil, a further relay carrying out the functions of switch C<SP>5</SP>. Specification 605,932 also is referred to.
